How is the single-blade centered after climbing to altitude?
The usual procedure after climbing to altitude is to briefly run at low power to avoid shock cooling the engine. The glider is re-trimmed after reducing power. When the ignition/fuel-injection switch is turned off (the master switch remains on) the propeller will windmill for a few revolutions (quantity depends on airspeed) and it will stop arbitrarily. At this point the blade-stop lever in the cockpit is moved forward and a corresponding flexible plastic tab located adjacent to the engine rotates forward into the plane of the propeller “arc”. Now it is a simple matter of looking in the small rear-view mirror located on the instrument panel and lightly tapping the starter button a few times until the propeller is in the 6 o’clock position and resting against the plastic tab. If the starter button is held too long the blade simply overshoots, the tab flexes out of the way, and the prop must be “bumped” all the way around by tapping the starter button again. When the blade is centered, t
